No. Surge is very bad right now. It's extremely expensive and has no other benefits. Entropy is BY FAR better at the moment.
But they are going to increase the duration of surge and will lower the cost, the 2 main downsides of Surge. So maybe this will finally make it viable. Not sure if it's enough though.

For Dungeons, Entropy will always be better, as it also increases your DPS. For pvp, Surge can be usefull, as it doesn't require an enemy to be there. So quite usefull out of stealth (not for stealth bonus of course, ranged spells don't benefit from stealth)

awesome answer, thank you! ill stick with entropy.

Thank you Another thing, few people know, is that there is no duration difference between entropy and surge.
Some people still use Surge, because they think, that the duration is longer....

The DoT of Entropy only lasts 14.4 seconds. But the actual spell damage buff lasts for around 21 seconds, compared to Surge, 23 seconds. Over 3000 Magicka for 23 seconds, or 400 Magicka for 21 seconds..... simple maths
